High Corrosion Resistance Magnets

High corrosion resistance magnets are designed to operate in the harshest of environments where magnets are most vulnerable to rusting. Nd–Fe–B sintered magnets have excellent magnetic properties such as wind turbines, electric vehicles, nuclear magnetic resonance apparatus, and communications. However, their relatively poor intrinsic coercivity (H cj) and poor anti-corrosion limit their applications in hot and humid environments. High corrosion resistance neodymium magnets are produced in a special process that makes them more resistant to corrosion than regular neodymium magnets. These magnets have significantly better results in salt spray tests. The magnetic characteristic of these magnets is quite similar to regular NdFeB magnets.
